The assessment of comprehensiveness of soil conservation measures (SCMs), along with economic, social, and environmental assessments of these projects, is a prerequisite for good governance in a watershed. This study was conducted using the cause-and-effect framework of DPSIR (Driver-Pressure-State-Impact-Response) to assess the comprehensiveness of SCMs in reducing the soil erosion potential of the Kond watershed area and its adverse impacts. Horticultural, mining, and ranching activities; population growth; and road network development were identified as the most important driving forces of the watershed. After determining the indicators, the integrated index was calculated based on weight calculation and standardization of values to detect changes before and after the implementation of SCMs. The results showed a decrease in soil erosion and the corresponding adverse impacts in 2019 compared with the base year, 1997, so that according to the integrated index, the soil erosion status and related impacts have decreased by 16 and 35%, respectively. Despite this decline, the watershed still has a high rate of soil erosion (26.27 t ha−1 year−1). This is because SCMs are more focused on improving the state and impacts, and there are no necessary managerial responses to the components of the driving forces and pressures. Given that the proactive approach has less contribution than the reactive approach in SCMs, in addition to the reactive approach, it is necessary to pay more attention to the proactive approach to reduce the soil erosion rate of the watershed and decrease the relevant negative impacts.

使用DPSIR框架评估土壤保护措施的综合性

对水土保持措施(SCM)的全面性进行评估,以及对这些项目进行经济,社会和环境评估,这是流域良好治理的前提。这项研究是使用DPSIR(驱动程序-压力-状态-冲击-响应)的因果框架进行的,以评估SCM在降低Kond流域地区的土壤侵蚀潜力及其不利影响方面的综合性。园艺,采矿和牧场活动;人口增长; 公路网的发展被认为是该流域最重要的驱动力。确定指标后,根据权重计算和值标准化来计算综合指数,以检测实施供应链管理前后的变化。结果表明,与1997基准年相比,2019年的水土流失有所减少,并产生了相应的不利影响,因此,按照综合指数计算,水土流失状况和相关影响分别减少了16%和35%。尽管下降,但流域的土壤侵蚀率仍然很高(26.27吨公顷-1-1)。这是因为SCM更加专注于改善状态和影响,并且对驱动力和压力的组成没有必要的管理响应。鉴于主动式方法在供应链管理中的作用要小于被动式方法,因此除了主动式方法外,有必要更加重视主动式方法,以减少流域的土壤侵蚀率并减少相关的负面影响。
